Textbook Neoadjuvant Experience: Defining a Novel Composite Outcomes Measure for Patients with Pancreatic Cancer Undergoing Neoadjuvant Therapy.

Background: Neoadjuvant therapy (NT) is increasingly utilized for patients with pancreatic ductal adenocarcinoma (PDAC). Disease progression, toxicity, and failure to undergo surgical resection are common during NT, yet little research has focused on efforts to optimize care delivery. We sought to define and validate a novel composite outcomes metric that characterizes the successful delivery of NT.

Precision Medicine for Metastatic Colorectal Cancer: Where Do We Stand?

Metastatic colorectal cancer is a leading cause of cancer-related death across the world. The treatment paradigm has shifted away from systemic chemotherapy alone to include targeted therapy and immunotherapy. The past two decades have been characterized by increased investigation into molecular profiling of colorectal cancer.

Glycated Hemoglobin A1c Time in Range and Dementia in Older Adults With Diabetes.

Importance: Individuals with diabetes commonly experience Alzheimer disease and related dementias (ADRD). Factors such as hypoglycemia, hyperglycemia, and glycemic variability have been associated with increased risk of ADRD. Traditional glycemic measures, such as mean glycated hemoglobin A1c (HbA1c), may not identify the dynamic and complex pathophysiologic factors in the association between diabetes and ADRD.

Resident and Fellow Performance and Supervision in Surgical Oncology Procedures.

Background: Previous research has highlighted concerns among trainees and attendings that general surgery training and fellowship are inadequately preparing trainees for practice. Providing trainees with supervision that matches their proficiency may help bridge this gap. We sought to benchmark operative performance and supervision levels among senior surgery residents (PGY-4 or -5) and fellows performing general surgical oncology procedures.

Simultaneous resection for colorectal cancer with synchronous liver metastases: current state-of-the-art.

Background: A large proportion of patients with colorectal cancer (CRC) presents with synchronous colorectal liver metastases (sCRLM) at diagnosis. Surgical approaches for patients with sCRLM have evolved over the past decades. Simultaneous resection (SR) of CRC and sCRLM for selected patients has emerged as a safe and efficient alternative approach to traditional staged resections.

Hepatic adenoma: evolution of a more individualized treatment approach.

Background: Hepatic adenomas (HAs) are benign, solid liver lesions, which carry a risk of hemorrhage and malignant transformation. This review article highlights the advances in the diagnosis and management of HAs.

Methods: A comprehensive review was performed using MEDLINE/PubMed and Web of Science databases with a search period ending on September 30, 2023.

Influence of Race/Ethnicity and Sex on Coronary Stent Outcomes in Diabetic Patients.

Background: How diabetes mellitus (DM), race/ethnicity, and sex impact ischemic events following coronary artery stent procedures is unknown.

Methods: Using the PLATINUM Diversity and PROMUS Element Plus Post-Approval Pooled Study (N = 4184), we examined the impact of race/ethnicity, sex, and DM on coronary stent outcomes. Primary outcome was 1-year major adverse cardiac events (MACE) (MACE composite: death, myocardial infarction [MI], and target vessel revascularization).

Nutrition Education and Nutrition Knowledge Among Obstetrics and Gynecology Residents.

Nutrition in pregnancy is a component of the Council on Resident Education in obstetrics and gynecology core curriculum; however, no studies currently examine adherence to this goal. Our objective was to assess obstetrics and gynecology (Ob/Gyn) residents' education and knowledge surrounding nutrition in pregnancy, including (1) amount of dedicated didactic time to and attitudes toward, (2) subjective comfort in counseling patients on, and (3) objective knowledge of pregnancy-related nutrition. This is a cross-sectional electronic survey-based study.

Infiltration of CD3+ and CD8+ lymphocytes in association with inflammation and survival in pancreatic cancer.

Background: Pancreatic ductal adenocarcinomas (PDAC) have heterogeneous tumor microenvironments relatively devoid of infiltrating immune cells. We aimed to quantitatively assess infiltrating CD3+ and CD8+ lymphocytes in a treatment-naïve patient cohort and assess associations with overall survival and microenvironment inflammatory proteins.

Methods: Tissue microarrays were immunohistochemically stained for CD3+ and CD8+ lymphocytes and quantitatively assessed using QuPath.

Update on Targeted Therapy and Immunotherapy for Metastatic Colorectal Cancer.

Metastatic colorectal cancer remains a deadly malignancy and is the third leading cause of cancer-related death. The mainstay of treatment for metastatic colorectal cancer is chemotherapy, but unfortunately, even with recent progress, overall survival is still poor. Colorectal cancer is a heterogeneous disease, and the underlying genetic differences among tumors can define the behavior and prognosis of the disease.

Discovery of KRB-456, a KRAS G12D Switch-I/II Allosteric Pocket Binder That Inhibits the Growth of Pancreatic Cancer Patient-derived Tumors.

Unlabelled: Currently, there are no clinically approved drugs that directly thwart mutant KRAS G12D, a major driver of human cancer. Here, we report on the discovery of a small molecule, KRB-456, that binds KRAS G12D and inhibits the growth of pancreatic cancer patient-derived tumors. Protein nuclear magnetic resonance studies revealed that KRB-456 binds the GDP-bound and GCP-bound conformation of KRAS G12D by forming interactions with a dynamic allosteric binding pocket within the switch-I/II region.

Changing Practice Patterns and Improving Survival for Patients with Pancreatic Ductal Adenocarcinoma.

Over the last two decades, there have been many reported advances in the clinical management of pancreatic ductal adenocarcinoma (PDAC). We sought to evaluate changes in survival for patients diagnosed with PDAC between 2004 and 2017. The National Cancer Database was queried for patients diagnosed with PDAC between 2004 and 2017.

One-year safety and effectiveness of the Agent paclitaxel-coated balloon for the treatment of small vessel disease and in-stent restenosis.

The Agent device consists of a semi-compliant balloon catheter, which is coated with a therapeutic low-dose formulation of paclitaxel (2 µg/mm) blended with an inactive excipient acetyl-tri-n-butyl citrate (ATBC). AGENT Japan SV is a randomized controlled study that enrolled 150 patients from 14 Japanese sites treated with Agent or SeQuent Please paclitaxel-coated balloon. This study also includes a single-arm substudy evaluating the safety and effectiveness of Agent in patients with in-stent restenosis (ISR).

A protein-based machine learning approach to the identification of inflammatory subtypes in pancreatic ductal adenocarcinoma.

Background/objectives: The inherently immunosuppressive tumor microenvironment along with the heterogeneity of pancreatic ductal adenocarcinoma (PDAC) limits the effectiveness of available treatment options and contributes to the disease lethality. Using a machine learning algorithm, we hypothesized that PDAC may be categorized based on its microenvironment inflammatory milieu.

Methods: Fifty-nine tumor samples from patients naïve to treatment were homogenized and probed for 41 unique inflammatory proteins using a multiplex assay.

Resource use for cholecystectomy with versus without cholangiography: A multicenter, propensity-matched analysis.

Background: Intraoperative cholangiography may allow for earlier identification of common bile duct injury and choledocholithiasis. The role of intraoperative cholangiography in decreasing resource use related to biliary pathology remains unclear. This study tests the null hypothesis that there is no difference in resource use for patients undergoing laparoscopic cholecystectomy with versus without intraoperative cholangiography.

mHealth Intervention for Promoting Hypertension Self-management Among African American Patients Receiving Care at a Community Health Center: Formative Evaluation of the FAITH! Hypertension App.

Background: African American individuals are at a higher risk of premature death from cardiovascular diseases than White American individuals, with disproportionate attributable risk from uncontrolled hypertension. Given their high use among African American individuals, mobile technologies, including smartphones, show promise in increasing reliable health information access. Culturally tailored mobile health (mHealth) interventions may promote hypertension self-management among this population.
